Whether you are planning to use Express Route or VPN tunnels to connect your data centers to Azure, and you want to use a co-location provider in your region to reach Azure or extend your MPLS network to Microsoft. Are you also thinking what is the optimal route to connect your regions?
These are the 4 questions to start with:
- Do you need dedicated, reliable connectivity and bandwidth?
- Do you need more than 1.25Gbps of bandwidth?
